Local Environmental Conditions
birch and oak lead the local pollen count in Turnhout, which sits on the sandy Campine plain near the Dutch border; grass pollen from the wider Antwerpen landscape adds to totals as spring gives way to summer. Exposure tends to track green space closely, with the busiest streets generally registering lower counts.
In Antwerpen, Turnhout experiences hazel and willow first, a birch and oak peak in the middle of spring, and grass pollen through early summer, spanning the January-to-August window. mugwort and ragweed extend exposure modestly into early autumn near open farmland. The town's position on the sandy Campine plain near the Dutch border plays into how the season plays out.

How often is the Turnhout pollen forecast updated?

Does pollen in Turnhout come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Turnhout based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Turnhout, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
